Localization of 18S + 28S and 5S ribosomal RNA genes in the dog by fluorescence in situ hybridization.
The gene clusters encoding 18S + 28S and 5S rRNA in the dog (Canis familiaris) have been localized by using GTG-banding and fluorescence in situ hybridization. The 18S + 28S rDNA maps to chromosome regions 7q2.5-->q2.7, 17q1.7, qter of a medium-sized, not yet numbered autosome, and Yq1.2-->q1.3. Our data show that there is one cluster of 5S rDNA in the dog, which maps to chromosome region 4q1.4.
